The invention belongs to the field of treating heavy oil, and relates to a preparation and application method of a surfactant. The surfactant is characterized by comprising the following components: 10-20% of phosphatide, 5-20% of tween-80, 5-20% of diethanolamine, 5-20% of AES (acrylonitrile), and the balance of water. The preparation method comprises the following steps: pouring the water into a reaction kettle, adding the quantitative diethanolamine and phosphatide to the reaction kettle at the same time, raising the temperature to 80 DEG C, and stirring the mixture for 2 hours at a constant temperature until the diethanolamine and the phosphatide are fully dissolved; adding the quantitative AES, raising the temperature to the range of 75 DEG C to 85 DEG C, and stirring for an hour at the constant temperature; then adding the tween-80, stirring for an hour at the constant temperature of 80 DEG C, reducing the temperature to 40 DEG C, and loading finished products into packing buckets according to measurement so as to obtain the finished products of the surfactant. The surfactant can be used as a thick oil viscosity-reducing agent, an asphalt emulsifying agent or an oil mixing agent for use. The surfactant has good emulsifiability and is wide in application field, heavy oil can be easily emulsified into the water through the surfactant, the viscosity reducing rate is as high as 99.99%, and the oil-water interfacial tension can be greatly reduced.

The invention provides an inland riverbank vegetation buffering and purifying zone, comprising: a riverbank vegetation buffering zone and a water and bank connection zone, wherein the riverbank vegetation zone has four layers, and a nonwoven earthwork cloth, a vegetation brick and a soil layer are laid from the ground in order. The water and bank connection zone comprises a broken stone bottom layer, nonwoven earthwork cloth, a broken stone inverted filter, ecology fish nest bricks, ecology retaining wall bricks and a coupling bar, wherein the broken stone bottom layer is laid on the river bottom, two ends of the broken stone inverted filter are connected to the nonwoven earthwork cloth layer and the broken stone bottom layer of the riverbank vegetation zone by a certain gradient, the nonwoven earthwork cloth is laid on the bottom of the broken stone inverted filter, the ecology fish nest bricks are laid on the upper of the broken stone inverted filter, the ecology retaining wall brick is used on the places approaching to the ground for protecting a dike, and the holes are arranged on the surface of the ecology retaining wall bricks. The riverbank vegetation buffering and purifying zone of the invention has advantages of big adaptation adaptive space, small land occupation, compact bank line arrangement, good landscape effect, mature technology and simple construction, and can not only satisfy the demand of water conservancy safety and landscape, bus also quicken establishment of a river ecology system, and improve and maintain water quality.

The invention relates to a preparation method of graphene antibacterial yarn. The prepared graphene oxide solution is poured into a dip tank, a vibrator at the bottom of the dip tank is turned on, and the padding coating is completed after the yarn is immersed in the dip tank for a preset time. , semi-drying; adding a photoinitiator to the prepared cinnamaldehyde solution, immersing the treated graphene yarn in the mixed solution, heating up and performing low-frequency ultrasonic vibration for a preset time, and placing it under a certain intensity of ultraviolet light to illuminate, The yarn is taken out for natural cooling, dried, shaped and wound to obtain graphene antibacterial yarn. The product prepared by the invention has bacteriostasis, heat preservation, double bacteriostasis and antiseptic ability, improves the peculiar smell produced by long-term storage of the yarn, and has deodorizing effect; the green and non-toxic additive of ultraviolet cross-linking method makes the components of graphene and cinnamaldehyde more firmly fixed On the yarn pores and surface, it is not easy to wash off during storage and later use, and the antibacterial aging effect is longer; the operation process is relatively simple and convenient, and it has a wider application space.

The invention relates to waste color raw material powder and application thereof. The waste color raw material powder is prepared through the following steps of (1) pretreatment of waste, except silica fume; (2) surface modification: on the premise of keeping original performance of building solid waste and industrial solid waste which are subjected to pretreatment, by a surface modification agent, performing surface modification agent on the building solid waste and industrial solid waste which are subjected to pretreatment, wherein the usage amount of the surface modification agent accounts for 0.1 to 3 percent of mass of the building solid waste and industrial solid waste which are subjected to pretreatment; (3) PH value adjustment: performing PH value adjustment on the obtained modified building solid waste and industrial solid waste, wherein the PH value is controlled to be 8 to 9, and the waste color raw material powder is obtained. According to the waste color raw material powder and the application thereof, the cost is low, the process is simple, product variety is achieved, the application range is wide, different kinds of materials are classified and separated out maximally, the classification effectiveness is improved, and the building solid waste and industrial solid waste are changed into wealth; the pollution problem of waste is solved, the waste color raw material powder and the application thereof are conducive to environmental protection and have obvious social benefit.
